Around 9:30 p.m. Wednesday, officers found a man shot in the chest in the 4900 block of Park Heights Avenue in northwest Baltimore, a few blocks south of Pimlico Race Course. The victim, identified as Austaniel Brown, 22, was taken to a hospital in critical condition and died about an hour later. So far, police have no suspects in the case.

Nearly two hours later, police on Park Heights Avenue investigating that shooting heard gunfire nearby. They said they found a man who had been shot in the torso in the 3200 block of Spaulding Avenue. The victim, identified Friday as Vernon Johnson, 27, was taken to an area hospital, where he died a short time later.

Anyone with information on either of those cases should call 410-396-2100.

Investigators are also searching for the gunman in an attempted robbery Wednesday afternoon in south Baltimore. The 36-year-old victim told police a man shot him in the face while trying to rob him shortly after noon in the 800 block of East Patapsco Avenue. The assailant then ran away.

The victim was taken to a nearby hospital, where he's still being treated. His condition isn't known. Anyone with information on that case should contact southern district detectives at 410-396-2499.

City detectives are also investigating the death of an infant in east Baltimore. Police said the child died around 3 p.m. Wednesday in the 900 block of East Preston Street. Officials originally ruled the death suspicious but said Thursday that that's no longer the case.

Officials are awaiting the results of an autopsy report to determine the child's exact cause of death.
